Asynonym for the word emphasis in paragraph 4 is
a)
equality.
b)
importance.
seriousness.
effectiveness.

B. Importance

Explanation:

Without having the paragraph itself to read, I will make my best educated guess.

Since the definition of emphasis is "special importance, value, or prominence given to something," I would imagine the answer is importance since it is in the definition.

If this is incorrect please add the paragraph to the question so we can have some context.
